1. What is an options account?
Each user owns a separate options account, in which one can use for fund guarantee and settlement in BTC and other cryptocurrencies. On all options trading pages, the following options account details are displayed (see below).
Investors are eligible for buying options only after activating OKEx options trading service. If they want to sell options, they need to apply for short qualification separately.
Investors can transfer funds between their options account, spot account, perpetual swap account, and futures account, etc. Before options contracts exercise and settle, they cannot transfer and withdraw the margin on hold and the profit from their options account during the current settlement cycle.
2. Options Account Introduction
The details of an options account are displayed on the trading interface, including account equity, account balance, available margin, used margin, maintenance margin ratio, realized profit and loss, unrealized profit and loss, and options market value.
Account Equity: The total sum of assets in an user’s options account
Account Equity = Account Balance + Options Market Value
Account Balance: The total amount of cryptoassets in an options account, including the margin on hold.
Margin: The funds that are on hold to make sure both counterparties can perform options trading normally and cannot be used for other purposes (buying, selling, holding and exercising options contracts upon expiry). The buyer’s margin type is different from the seller’s. For buyers, margin is required to place orders but not to hold positions. For sellers, margin is required to place orders and hold positions.
Available Margin: The margin available for opening positions
Used Margin: The margin required by open positions and all open orders.
Maintenance Margin: The minimum margin required for maintaining all current open positions in an account. Partial liquidation will be triggered if the Account Balance falls below the Maintenance Margin.
Realized Profit and Loss (RPL): The profit and loss generated by positions closed between last settlement and current time. RPL will count towards users' equity, and can serve as position margin but cannot be withdrawn. Withdrawal of realized profit is available after settlement.
Unrealized Profit and Loss (UPL): The profit and loss generated by the open positions between current time and the last settlement.
Options Value: The market value of the options positions held
Options Value = mark price * contract multiplier * amount of contracts held
